DETAILED DESCRIPTION

It should be understood at the outset that although illustrative implementations of one or more embodiments are illustrated below, the disclosed systems and methods may be implemented using any number of techniques, whether currently known or not yet in existence. The disclosure should in no way be limited to the illustrative implementations, drawings, and techniques illustrated below, but may be modified within the scope of the appended claims along with their full scope of equivalents.

The pending disclosure is directed to an eyeglass frame lens lock that enables the lenses to removed and placed into a different eyeglass frame or the lenses to be removed and different lenses placed into the same eyeglass frame in an easier and more efficient way. For example, the eyeglass frame lens lock disclosed herein mechanically works to allow the removal of a lens with a simple manual action and without tools to release the lens. The eyeglass frame lock at least partially encloses or captures a portion of a split rim. The eyeglass frame lock closes the split rim to contain and secure the lens within the eyeglass frame.

In an embodiment, an eyeglass frame may comprise two eyeglass frame lens locks that each couple one temple to one split rim. In another embodiment, an eyeglass frame may comprise one or more eyeglass frame lens locks on the bridge of the eyeglass frame. For instance, the bridge of the eyeglass frame could form a single eyeglass frame lens lock that captures and constrains both split rims. In another example, the bridge of the eyeglass frame could comprise two eyeglass frame lens locks with each lock capturing and constraining one split rim and coupling the split rim to the bridge. In yet another example, an eyeglass frame may comprise two eyeglass frame lens locks elsewhere on the eyeglass frame as a decorative extension such as in corners of a cat eye style of eyeglass frames that each captures and closes a split rim to contain and secure the lens within the eyeglass frame and opens the split rim and releases the lens without requiring the use of tools.

The eyeglass frames discussed herein may be manufactured using one or more materials that are formable with a memory or resilience to elastically respond towards an original state even after being locked in a different state for a period of time to allow for easy removal of the lenses. For example, the split rims may be manufactured such that the rims naturally open at the split when the split rim is removed from the eyeglass frame lens lock.

The ability to easily release the lenses from within an eyeglass frame with only manual action using the disclosed eyeglass frame lens lock provides a number of different advantages and opportunities. For example, an eyeglass wearer could treat eyeglass frames as more of a fashion accessory by moving their lenses from one eyeglass frame to another eyeglass frame. For instance, an eyeglass wearer may want to wear a different color eyeglass frame based on their outfit choice for the day or may want to wear a different style eyeglass frame for a night out, and the eyeglass frame lens lock disclosed herein would allow them to easily remove the lenses from one eyeglass frame and place them in a different color or different style eyeglass frame. In another example, an eyeglass wearer may want to move their lenses from one eyeglass frame to another eyeglass frame for a more practical reason. For instance, an eyeglass wearer may want to wear a different style of eyeglasses for safety reasons, and the eyeglass frame lens lock disclosed herein would allow them to easily remove the lenses from one eyeglass frame and place them into a different, safety type eyeglass frame.

In addition to being able to remove lenses and place the lenses in a different eyeglass fame, the eyeglass frame lens lock disclosed herein also allows different lenses to be placed into the same eyeglass frame. For example, the eyeglass frame lens lock would enable an eyeglass wearer to remove and replace lenses having coatings and treatments that are optimized for indoor use from their eyeglass frames with lenses having coatings and treatments that are optimized for outdoor use when they are outside. In another example, the eyeglass frame lens lock would enable an eyeglass wearer to remove and replace lenses used for reading with lenses used for driving when they leave work to drive home.

Having the disclosed eyeglass frame lens locks located on the temples of the eyeglasses has a number of benefits. For example, such placement enables a seamless transition of the temples without needing to substantially change the look of the eyeglasses. The eyeglass frame lens locks and the placement of such locks at the temples may also strengthen the connection of the temples with the rims. Further, placing the hinges behind the eyeglass frame lens locks may help reduce the chances of damaging the eyeglass frame lens locks and the connection point of the rims and the locks due to bending of the temples at the hinge.

Turning now to FIGS. 1A-1C, an embodiment of an eyeglass frame 100 is illustrated. The eyeglass frame 100 may be made out of plastic, metal, wood, 3D printing compounds, or a different material. In an embodiment, the eyeglass frame 100 comprises a bridge 102, two rims 104, two lenses 106, two temples 108, two earpieces 110, and two hinges 112. The bridge 102 may comprise an arched piece in a front center of the eyeglass frame 100. The bridge 102 may rest on a wearer's nose and connect the rims 104. Each of the rims 104 may be configured to contain or hold one of the lenses 106. In an embodiment, the rims 104 may be configured to rest on a wear's nose. In regard to shape, the rims 104 may be circular, oval, rectangular, square, or a different shape.

The lenses 106 may be clear or tinted material. The lenses 106 may be made of plastic, polycarbonate, or different material. The lenses 106 may be prescription lenses.

In an embodiment, the temples 108 comprise arms on the sides of the eyeglass frame 100 that extend from the hinges 112 and over the wearer's ears to keep the glasses on the wearer's face. The temples 108 may comprise the earpieces 110, which rest on and/or behind the wearer's ears. In an embodiment, the earpieces 110 comprise a cover over the end of the temples 108 to provide more comfort to the wearer. The hinges 112 may comprise a movable joint that allows the temples 108 to fold inward.

In an embodiment, the eyeglass frame 100 also comprises two split end pieces 114. Each split end piece 114 may be coupled to and extend outward from one of the rims 104 on a side of the rim 104 opposite the bridge 102. Each of the split end pieces 114 may comprise a first portion 114 a and a second portion 114 b. Each rim 104 on a side opposite the bridge 102 may comprise a horizontal split 116 to allow removal of the lens 106. In an embodiment, the first portion 114 a of the split end piece 114 is coupled to the rim 104 on one side of the split 116 while the second portion 114 b of the split end piece 114 is coupled to the rim 104 on the other side of the split 116. The split end pieces 114 may be formed together with the rims 104 as part of the manufacturing processes. Alternatively, the split end pieces 114 may be coupled to the rims 104 during or after the manufacturing process.

The eyeglass frame 100 may also comprise two locks 118. Each lock 118 may be located on an end of a temple 108 closest to the rims 104. In an embodiment, each lock 118 is configured to at least partially contain both the first portion 114 a and the second portion 114 b of the split end piece 114 and secure the temple 108 to the rim 104 and secure the lens 106 within the rim 104. The hinges 112 discussed above may be located at a back of the locks 118 closest to the earpieces 110 of the temples 108.

Each lock 118 may comprise a spring 120. In an embodiment, the spring 120 is a compression spring. In other embodiments, the spring 120 may be a different type of spring. The lock 118 will be discussed in more detail below with reference to FIGS. 3A and 3B.

In an alternative embodiment, rather than each lock being located on an end of a temple 108 closest to the rims 104, the eyeglass frame 100 may comprise two locks elsewhere on the eyeglass frame 100 as a decorative extension such as in corners of a cat eye style of eyeglass frames. Similar to lock 118, each lock in a corner of the rims 104 opposite the bridge 102 may capture and close the split 116 in the rim 104 to contain and secure the lens 106 within the eyeglass frame 100 and open the split 116 in the rim 104 and release the lens 106.

Turning now to FIGS. 2A and 2B, an embodiment of the spilt end piece 114 is illustrated. At least one of the first portion 114 a or the second portion 114 b may comprise a protrusion or a lug 202. A lug 202 as described further herein may be configured to travel through a channel and engage with a shoulder to create a retaining force.

In an embodiment, as illustrated in FIG. 2B, both the first portion 114 a and the second portion 114 b comprise a lug 202. For example, the first portion 114 a may comprise a lug 202 a on a top of the first portion 114 a while the second portion 114 b may comprise a lug 202 b on a bottom of the second portion 114 b. The lug 202 may be orthogonal in shape or curved. Each of the first portion 114 a and the second portion 114 b may comprise an exposed portion 204 and an end portion 206.

While illustrated in FIGS. 2A and 2B as being approximately centered on the exposed portion 204 of each split end piece 114, the lug 202 could be located closer to one of the ends of the split end piece 114 without departing from the spirit or scope of the present disclosure. In an embodiment, the exposed portion 204 may be semi-circular in shape. Alternatively, the exposed portion 204 may comprise a different shape.

The end portion 206 of each split end piece 114 may be disposed within the rim 104, and therefore not exposed. While illustrated in FIGS. 2A and 2B as being L shaped, the end portion 206 of each split end piece 114 may comprise a different shape without departing from the spirit or scope of the present disclosure.

Turning now to FIGS. 3A and 3B, an embodiment of the lock 118 is illustrated. In an embodiment, the lock 118 comprises a passageway 302 through which the split end piece 114 travels. The lock 118 may comprise at least one channel 304 defined by at least one surface of the lock 118. The at least one channel 304 may be configured to receive at least some of the first portion 114 a or the second portion 114 b of the split end piece 114. For example, the at least one channel 304 may receive the lug 202 a of the first portion 114 a or the lug 202 b of the second portion 114 b of the split end piece 114. The lock 118 may also comprise at least one shoulder 306 comprising a surface of the lock 118. The at least one shoulder 306 may be configured to receive and engage the lug 202. The at least one shoulder 306 may comprise an orthogonal shoulder profile. Alternatively, the at least one shoulder 306 may comprise a non-orthogonal shoulder profile, for example, to mate with a curved lug. While illustrated as being rectangular in shape, the lock 118 could comprise a different shape without departing from the spirit or scope of the present disclosure.

As illustrated in FIG. 3B, in an embodiment, the passageway 302 of the lock 118 comprises a pair of channels 304 a and 304 b beginning at an entrance of the lock 118 and defined by a plurality of surfaces of the lock 118. Each channel 304 a, 304 b may be configured to receive a corresponding lug 202 a, 202 b of a corresponding portion 114 a, 114 b of the split end piece 114. The spring 120 within the lock 118 may be configured to compress as the first portion 114 a and the second portion 114 b of the split end piece 114 are inserted into the lock 118 and each lug 202 a, 202 b is moved through a corresponding channel 304 a, 304 b toward a back of the lock 118.

With reference now to FIGS. 4A and 4B, an embodiment illustrating the split end piece 114 locked within the lock 118 is shown. In addition to a pair of channels 304 a, 304 b, the lock 118 may also comprise a pair of shoulders 306 a, 306 b toward the back of the lock 118. Each shoulder 306 a, 306 b may comprise a surface of the lock 118 and may be configured to receive and engage the corresponding lug 202 a, 202 b. The surface of each shoulder 306 a, 306 b may be adjacent to at least one of the plurality of surfaces defining the pair of channels 304 a, 304 b. In an embodiment, the surface of each shoulder 306 a, 306 b is approximately perpendicular to at least one of the plurality of surfaces defining the pair of channels 304 a, 304 b. For example, the surface of each shoulder 306 a, 306 b may be about 85 degrees to 95 degrees from at least one of the plurality of surfaces defining the pair of channels 304 a, 304 b.

To lock the split end piece 114 into the lock 118 and thereby secure the temple 108 to the rim 104 and secure the lens 106 within the rim 104, the split end piece 114 and/or the lock 118 may be rotated to align the lugs 202 a, 202 b with the pair of channels 304 a, 304 b. Once aligned, the split end piece 114 may be inserted into the passageway 302 and the lug 202 a of the first portion 114 a of the split end piece 114 may travel through one of the channels 304 a, 304 b and the lug 202 b of the second portion 114 b of the split end piece 114 may travel through the other of the channels 304 a, 304 b. As the first portion 114 a and the second portion 114 b of the split end piece 114 are inserted into the lock 118 and each lug 202 a, 202 b is moved through a corresponding channel 304 a, 304 b toward a back of the lock 118, the spring 120 may compress.

Once the lugs 202 a, 202 b reach the end of the pair of channels 304 a, 304 b, the split end piece 114 and/or the lock 118 may be rotated until the lugs 202 a, 202 b engage with the corresponding shoulder 306 a, 306 b. For example, in an embodiment, the split end piece 114 and/or the lock 118 are rotated approximately 90 degrees for the lugs 202 a, 202 b to engage with the shoulders 306 a, 306 b. Once engaged, the spring 120 may be released thereby securing the lugs 202 a, 202 b against the shoulders 306 a, 306 b and locking the split end piece 114 within the lock 118. With the split end piece 114 locked within the lock 118, the temple 108 is secured to the rim 104 and the lens 106 is secured within the rim 104.

Turning now to FIGS. 5A-5C, an embodiment of the eyeglass frame 100 is illustrated showing how to remove the lens 106 from the rim 104. In order to remove the lens 106 from the rim 104, the split end piece 114 has to be disengaged from within the lock 118. To disengage the split end piece 114 from within the lock 118, the temple 108 may be pushed toward the rim 104 to compress the spring 120 and disengage the lugs 202 a, 202 b from the shoulders 306 a, 306 b. Next, as illustrated in FIG. 5A, the temple 108 may be rotated until the lugs 202 a, 202 b align with the pair of channels 304 a, 304 b. In an embodiment, the temple 108 may be rotated approximately 90 degrees for the lugs 202 a, 202 b to move into the pair of channels 304 a, 304 b.

As illustrated in FIG. 5B, the split end piece 114 may be pulled out of the lock 118 by pulling the lugs 202 a, 202 b through the pair of channels 304 a, 304 b. Once the split end piece 114 is removed from the lock 118, the rim 104 may be opened at the split 116 as illustrated in FIG. 5C. For example, the rim 104 may be opened at the split 116 by separating the first portion 114 a of the split end piece 114 from the second portion 114 b of the split end piece 114. The lens 106 may then be removed from the rim 104. Once removed, the lenses 106 may be placed into a different eye glass frame.

For example, in an embodiment, the eyeglass frame 1200 comprises a bridge 1202, two rims 1204, two lenses 1206, two temples 1208, two earpieces 1210, and two hinges 1212. The eyeglass frame 1200 may be made out of plastic, metal, wood, 3D printing compounds, or a different material.

The difference between eyeglass frame 100 and eyeglass frame 1200 is that eyeglass frame 1200 may comprise (1) two split pieces 1214 on a same side of the rim 1204 as the bridge 1202 as opposed to two split end pieces on a side of the rim 1204 opposite the bridge 1202 and (2) at least one lock 1218 on the bridge 1202 as opposed to a lock on each temple 1208. Each split piece 1214 may be coupled to and extend outward from one of the rims 1204 on a same side of the rim 1204 as the bridge 1202. Each of the split pieces 1214 may comprise a first portion 1214 a and a second portion 1214 b. Each rim 1204 on a same side as the bridge 1202 may comprise a horizontal split 1216 to allow removal of the lens 1206. In an embodiment, the first portion 1214 a of the split piece 1214 is coupled to the rim 1204 on one side of the split 1216 while the second portion 1214 b of the split piece 1214 is coupled to the rim 1204 on the other side of the split 1216. The split pieces 1214 may be formed together with the rims 1204 as part of the manufacturing processes. Alternatively, the split pieces 1214 may be coupled to the rims 1204 during or after the manufacturing process. The at least one lock 1218 on the bridge 1202 may be configured to at least partially contain both the first portion 1214 a and the second portion 1214 b of at least one of the two split pieces 1214 and secure the lens 1206 within the corresponding rim 1204.

In an embodiment, the bridge 1202 comprises two locks 1218 a, 1218 b. The first lock 1218 a may be configured to at least partially contain both the first portion 1214 a and the second portion 1214 b of a first of the two split pieces 1214 and secure a first lens 1206 within a first of the two rims 1204 and the second lock 1218 b may be configured to at least partially contain both the first portion 1214 a and the second portion 1214 b of a second of the two split pieces 1214 and secure a second lens 1206 within a second of the two rims 1204. In an embodiment, as illustrated in FIG. 12, the locks 1218 a and 1218 b are substantially similar to the locks 118 discussed above in FIGS. 3A, 3B, 4A, and 4B. In an alternative embodiment, when the at least one lock 1218 is on a same side as the bridge 1202, the lock may be mechanically simpler than locks 118. For example, the at least one lock 1218 may clasp over the first portion 1214 a and the second portion 1214 b of at least one of the two split pieces 1214. Also, while illustrated in FIG. 12 as two locks 1218 a and 1218 b, in an embodiment, there may be only a single lock on a same side as the bridge 1202 and that single lock may clasp over the first portion 1214 a and the second portion 1214 b of both of the two split pieces 1214.
